    Abstract

    We demonstrate experimentally an optical switch architecture that employs μm-SOI-based circuitry for both buffering and routing purposes and operates with 10 Gb/s optical packets in both uni- and multi-cast switching forwarding modes. It comprises a hybrid Broadcast-and-Select (BS) / wavelength-routed architecture, with the BS layout being responsible for identifying the desired cluster of outgoing ports, while the wavelength-routed switch part forwards then the data to the specific outgoing port. Contention resolution at the BS switch part is offered through an μm-SOI integrated optical delay line bank and wavelength-routing is realized by means of a μm-SOI 3×3 Echelle grating router, while SOA-MZIs are employed for wavelength conversion purposes. The switch architecture has been experimentally validated with 10 Gb/s optical data packets for both uni- and multicasting operation, revealing error-free performance with <5 dB power penalty.
